  • I’m comparing gender identity to other forms of protected identity: race, ethnicity, sexual orientation, etc.

    I’m not making any judgements about any group being superior or inferior to another. You’re the one doing that. Being “physically imposing” is subjective and variable. There is significant overlap between the largest women and smallest men, and that’s just staying withing the confines of binary cis people. Not to mention… Guns exist. Cars themselves are weapons far more dangerous than any human regardless of gender.

    Building a just society means we need to leave behind our biases and fears. To judge individuals not on the circumstances of their birth but the content of their character. That means discarding the luxury of pre-judging people, not just when it is easy, but also when it is hard.



  • It’s shocking to me how so many people I know who are woke as fuck and quick to shout down any bigotry are so quick to drop all of their principles to hate men.

    Segregation never works, and only serves to foster fear, hatred, and division within society You cannot define what a “woman” is in a way that excluded trans-women without also excluding some cis-women with them Your gender identity is what you say it is. Others should do their best to remember any pronouns or name changes Crime is too complicated and nuanced to be reduced to statistics, which are often used by racists and bigots to justify racist and bigoted policies It’s racist to cross to the other side of the street when a person of color comes walking towards you on the side you currently are on. It’s up to you to “Men” are evil monsters who cannot be trusted and need to be locked away

    It baffles me how so many people can have all of these ideas, including the last one, and not see the cognitive dissonance there. It’s succumbing to fear and hatred, the same methods of divisive propaganda that has harmed every other group.






  • For those who don’t want to read several pages of unnecessary text telling you what you probably already know:

    The math, while pretty involved, may tell a straightforward story (if you’re interested in the details of our analysis, see the Appendix). OpenAI has contracted 900K memory wafers per month from Samsung and SK Hynix. Partner commentary seems to indicate that’s a monthly number, so that represents 10.8 million wafers over 12 months. In terms of demand, a fully built-out 10GW Stargate cluster would require ~3 million GB200 Bianca Boards. Each board requires ~50% of a memory wafer in total; split between the HBM3e stacks embedded into its two B200 GPU (~30%) and its 480 GB of LPDDR5X system memory (~20%). That puts total wafer demand for the entire cluster at ~3 million wafers.

    Therefore, according to our best estimates, OpenAI likely needs less than 30% of the 10.8 million wafers it’s planning to buy

    So this is just putting some numbers to what a lot of people already guessed. The AI companies are not just buying a ton of RAM to build out their data centers. They aren’t buying enough other components to even use that RAM. They’re buying it so that no one else can.










  • I know the general idea is to make it easier for your body to enter fat burning mode “ketosis” which iirc means that if you hit a calorie deficit

    That is not the goal of keto at all. People can choose to add calorie counting, but that’s an additional step. Calories are a unit of thermal energy. It’s how much energy is released when the food is burned (more technically, oxidized). The most basic way to measure this is to burn it in a way that directs the thermal energy to a container of water, where it’s then pretty straightforward to measure the temperature change and do the math.

    As a vague heuristic to measure the energy in food this is… Sometimes useful, sometimes not. What your body actually does is break down carbs into glucose, and things like protein, fat, and alcohol to ketones. Those eventually get broken down further into Adenosine triphosphate, or ATP, which is the basic fuel source your cells mostly use to do things. This is not the same as an oxidation reaction.

    More importantly though, when you reduce caloric intake you risk some negative outcomes, which is where we start to mix between physiological and psychological. A lot is based on genetics: if you are lucky enough to have the right genes, you can reduce caloric input or increase caloric output and see weight loss results. Unfortunately, a lot of people like myself don’t have such genes. Instead, when we reduce calories are bodies starts to use processed designed to survive famines- slowing the metabolism, reducing the amount of energy expended, storing as much energy as possible (as fat). If you stick to it long enough, you will lose weight eventually. The problem is that your body makes it harder to stick to it.

    Hunger is one of the most basic, primal driving factors baked into the relationship between our body and mind. Caloric restriction can make people hungrier. It causes a lot of diets to fail. It also makes it hard to keep the weight off.

    What keto does is gets your body used to treating fat as a source of energy to be used rather than stored for later. So I don’t have to count my calories, I just make sure that what I’m eating has relatively few carbs. Personally, I prefer protein-heavy foods over fat-heavy, although some keto people would argue that doesn’t count as strictly “keto” anymore. It’s not because I’m a gymbro who needs protein, but because protein makes me feel full and satisfied. I don’t have to count calories. I don’t have to be hungry. I don’t have to keep track of every little thing that I eat and think about whether I can afford to have a drink at the end of the night. Compared to caloric restriction (weight watchers), the minute-to-minute decisions are way easier and the day-to-day decisions go away.

    It’s not for everyone of course. The academic research, like with every other diet, is mixed. When you get off keto you’ll probably gain some weight back. I’m sure there are some medical conditions that it makes worse. My wife happens to have a lot of issues that are improved by keto (epilepsy and PCOS. Kidney stones too, though the research on that is more mixed).
